Grammarly Free

Grammarly Free costs $0 and provides spelling and grammar corrections, tone detection and 100 generative-AI prompts per month. The prompt allowance automatically refills monthly based on the date generative AI first became available on the account, and Grammarly says account holders in any country can access its generative assistance.

Free users do not receive full-sentence rewrites, adjustable tone, fluency suggestions, plagiarism checking, AI-text detection, brand controls or the 2,000-prompt paid allowance. A prompt can consume allowance even when used inside a supported application, and no extra Free prompts are offered after exhaustion until the refill. Prompt text and relevant context are shared with Grammarly’s service partners to provide generative features.

Individuals who mainly need routine spelling, grammar and tone checks with occasional AI drafting or revision assistance.
